Like heat and light, sound is also a form of _______

Options

A. radiation
B. energy
C. motion
D. force

Answer

**Step-by-Step Solution:**

1. **Understanding Heat and Light**:
- Heat and light are forms of energy. They can be defined as the ability to do work or produce change.

2. **Identifying the Nature of Sound**:
- Sound is classified as a mechanical wave. This means it requires a medium (like air, water, or solids) to propagate.

3. **Defining Mechanical Waves**:
- Mechanical waves are disturbances that travel through a medium due to the vibrations of particles within that medium.

4. **Explaining Sound Propagation**:
- When sound travels, it causes the particles in the medium to vibrate. For example, when a tuning fork is struck, its prongs vibrate, pushing against air molecules and causing them to move.

5. **Energy Transfer in Sound**:
- The energy from the vibrating prongs of the tuning fork is transferred to the air molecules, causing them to vibrate as well. This transfer of energy is what allows sound to propagate through the medium.

6. **Conclusion**:
- Since sound involves the transfer of energy through vibrations in a medium, we can conclude that sound is indeed a form of energy, similar to heat and light.

**Final Answer**: Like heat and light, sound is also a form of **energy**.
